Over two years, VolkerRail  completed all design and construction works, including p.way, signalling and OLE, for the new single electrified track. The new line, which has been built partly on the new viaduct and partly over the new chalk filled embankment, has been given the name Down Cambridge Flyover.

VolkerRail also constructed two new junctions which link the East Coast Main Line (ECML) and the Down Cambridge Flyover to the Cambridge line. This allows Cambridge bound trains from London to pass over the top of the ECML, thus increasing their reliability and improving capacity on the network.

Steve Cocliff, managing director at VolkerRail, commented: "This project has been a great opportunity for VolkerRail. It has allowed us to showcase not only our capabilities in track construction and overhead line electrification, but also our experience in collaboration and integrated project teams."

The main contract for VolkerRail commenced in August 2011 and was commissioned June 2013, five months ahead of schedule.
